[
\text{ROI} = \frac{(\text{Total Savings} – \text{Total Costs})}{\text{Total Costs}} \times 100
]

In this context, total savings would encompass energy bill reductions, plus any revenue accrued from selling back excess power to the grid and financial benefits derived from governmental incentives. Meanwhile, total costs cover the entire financial footprint connected with the installation, including acquisition, installation, maintenance, and any ancillary costs that may arise.

The final value yielded from this formula will present potential investors with a percentage indicating the return on their Powerwall investment. A positive ROI suggests that the investment is ultimately profitable, while a negative figure indicates a loss, thus urging a reevaluation of the business case.
